Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986566, here are decompositions:

3 + 986563 = 986566
23 + 986543 = 986566
47 + 986519 = 986566
59 + 986507 = 986566
89 + 986477 = 986566
137 + 986429 = 986566
149 + 986417 = 986566
197 + 986369 = 986566

Showing the first eight; more decompositions exist.
